The fact that the tails of a normal distribution never touch the horizontal axis relates to ______ property.
The fact that the tails of a normal distribution never touch the horizontal axis relates to the asymptotic property.
What is the normal distribution?The normal distribution or bell-shaped curve are other names for the Gaussian distribution. The mean divides the normal distribution into two equal pieces, making the mean symmetrical. In a normal distribution, the mean determines the curve's height, while the standard deviation determines its width.
So the tails on a normal distribution go on forever and never touch the x-axis.
Therefore, the fact that the tails of a normal distribution never touch the horizontal axis relates to the asymptotic property.

Answer:

Step-by-step explanation:
use PEMDAS
start with the exponent: (-4)^2=16
-12 / 3 * (-8 + 16 - 6) +2
then the parentheses: (-8+16-6)=2
-12 / 3 * 2 +2

Greg ate 1/6 of a pizza. afterward, steve ate 1/3 of the remaining pizza. what fraction of the pizza was left after that?
Answer: 1/2
1/3 = 2/6, and 2/6 + 1/6 = 3/6. Since 3/6 can be simplified to 1/2, there would be half of a pizza left.

Which ones are the correct answers
The result obtained are-
smallest value = 4.largest value = 48.median = 24first quartile {Q1} = 12third quartile {Q3} = 36What is defined as the frequency table?A frequency table is merely a "t-chart" or two-column table that illustrates the numerous possible outcomes and associated frequencies demonstrated in a sample.
Part 1: Smallest value;
As the frequency table is continuous distribution with a initial value of 4.
Thus, the smallest value of the table is 4.
Part 2: largest value;
As the frequency table is continuous distribution with a final value of 48.
Thus, the largest value of the table is 48.
Part 3: Median
The median is the number in the middle of a sorted list of numbers, and it is more descriptive of the data set than that of the average.
For even number of frequencies.
median = n/2
median = 12/2 = 6
Thus, the 6th term is the median.
median = 24.
Part 4: first quartile {Q1}
When data points are organized in increasing order, the lower quartile, or the first quartile (Q1), is indeed the value at which 25% of them are found.
Thus, Q1 = 12.
Part 3: third quartile {Q3}
When arranged in increasing order, the upper quartile, as well as third quartile (Q3), has been the value at which 75% of data points are found.
Q3 = 36.
The result for the frequency distribution is obtained.

Explain why researchers formulate a null hypothesis in addition to a hypothesis when designing an experimental study.
A null hypothesis outlines what a researcher should see if the tested hypothesis is incorrect. In essence, it presents an "alternative" theory to the first.
What is the null hypothesis?The null hypothesis is a type of hypothesis that explains the population parameter and is used to examine if the provided experimental data are reliable. Depending on whether the population or sample under consideration is viable, this hypothesis is either rejected or not. Or to put it another way, the null hypothesis is a hypothesis that assumes that the sample observations are the result of chance. It is claimed to be a claim made by surveyors who wish to look at the data.
The basic idea behind null hypothesis testing is to gather data and calculate the probabilities of a particular set of data during an experiment on a random sample, presuming that the null hypothesis is correct.

Splash city water park has 14 different rides. Each customer goes on an average of 8.4 rides, with standard deviation of 2. The distribution of rides customers go on is normal. What percent of the riders go on more than 10 rides? Round to the nearest percent.
Using the normal distribution, it is found that 21% of the riders go on more than 10 rides.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 8.4, \sigma = 2[/tex]
The proportion of riders that go on more than 10 rides is one subtracted by the p-value of Z when X = 10, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (10 - 8.4)/2
Z = 0.8
Z = 0.8 has a p-value of 0.7881.
1 - 0.7881 = 0.2119 = 21.19% = 21%(rounded to the nearest percent)
21% of the riders go on more than 10 rides.

A zero-order reaction of reactant a is found to have [a]0=0.25 m. if [a]=0.10 m at t=100. s, what is the rate constant k?
The rate constant K is 0.0015.
Zero-order reaction of reactant a is found to have [a]0=0.25 m and
if [a]=0.10 m at t=100s, then we need to find the rate constant k.
What is the formula for rate constant k?The rate constant, k, is a proportionality constant that indicates the relationship between the molar concentration of reactants and the rate of a chemical reaction
k=([a]0-[a])/t
where k is rate constant,
By the given data we have [a]0=0.25 m
[a]=0.10 m
t=100s
k=?
The rate constant, is a proportionality constant that indicates the relationship between the molar concentration of reactants and the rate of a chemical reaction.
The rate constant is denoted by k.
k=([a]0-[a])/t
Subtract 0.10 from 0.25 and divide it by 100
=(0.25-0.10)/100
=0.15/100
=0.0015
Therefore 0.0015 is the rate constant when a zero-order reaction of reactant a is found to have [a]0=0.25 m and [a]=0.10 m at t=100.
